CHHVINEY AND VENTILATOR TOP.

SPECIFICATION forming part of Letters Patent N0. 317,973, dated May 19,1885.

Application filed January 31, 1885. (N0 model.)

To aZZ whom it may concern:

Be it known that I, CONRAD HEINRIOH CASSELMANN, acitizen of the UnitedStates of America, residing at Eliingham, in the county of Effingham andState of Illinois, have invented certain new and useful Improvements inChimney and Ventilator Tops,of which the following is a specification,reference being 1 al therein to the accompanying drawings.

My invention relates to certain improvements in chimney-tops.

The object of theinvention is to so construct a chimney-top as to moreperfectly regulate the draft, to prevent the collection of soot in thechimney, and, when the device is used in connection with a movableengine, to provide a suitable spark-arrester.

To the accomplishment of the above,the invention consists in placing inthe top of the chimney or stack a pipe provided with a series of flaringbranches or nozzles, into each of which is inserted a funnel-shapedpipe, the inner ends of these pipes occupying a position over thevertical branch of the pipe and being suitably bent to prevent themcontacting with each other. These funnel-shaped pipes protrude a shortdistance out beyond the outer ends of the main-pipe branches and aresupported upon suitable lugs, the spaces between the branch pipes andthe funnel-shaped pipes being covered by suitable wire-cloth when thedevice is used in connection with the stack of a movable engine.

Reference will be made to the accompanying drawings,in which Figure 1 isan elevation of the device, and Fig. 2 a sectional plan thereof.

Like letters refer to like parts in both views.

In the drawings, A represents a'pipe which is adapted to be insertedinto the top of a chimney or smokestack.

Secured to the upper end of pipe A, and opening into it, are a series ofbranch pipes or nozzles, B, there being four of such pipes shown, butany desired number may be used. Each branch B is preferably provided atits outer end with a flaring collar,b, and into each of such branchesthere is inserted a funnelwith the Smokestack of a movable engine, I

the space formed between the outer end of each branch B and thecorresponding pipe 0 may be covered by a wire screen, D, as shown in thedrawings, this arrangement effectually covering the points at which thesparks would be most liable to escape.

Bythe arrangement of theparts as described, it will be seen that thedraft entering the chi1nney is perfectly controlled,and while a strongdraft is provided,the chimney or stack is thoroughly protected from anysudden gusts of wind.

What I claim is l. A chimney-top consisting of a pipe to be insertedinto the chimney, a series of branchescommunicatingtherewith,andafunnel-shaped pipe supported in eachbranch,as set forth.

2. A chimney-top consisting ofa pipe to be inserted into the chimney, aseries of branches communicating therewith, and a funnel-shaped pipesupported in each branch, the contracted ends of the funnel-shaped pipesbent, as described and shown.

3. A chimney-top consisting of a pipe to be inserted into the chimney, aseries of branches communicating therewith, and a funnel-shaped pipesupported in each branch, the branches and funnel-shaped pipes beingseparated by wire screens,as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
